5. Fish
Oily-fish, (Salmon, sardines, herring, trout, mackerel, anchovies, and cod) and non-oily fish, (tilapia, rock fish, seabass, etc.) represent a vitally important source of healthy fats and minerals. Omega 3 and omega 6 fatty acids found in fish are well-renowned for their ability to nourish the heart, brain, and liver, and to stave off heart disease and neurodegenerative diseases like Alzheimer’s.
